Opinion polling on the presidency of Aníbal Cavaco Silva was regularly conducted by Portuguese pollsters during his term in office between March 2006 and March 2016.

Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading opinion colour. In the instance that there is a tie, then no figure is shaded but both are displayed in bold. The lead column on the right shows the percentage-point difference between the two options, approval and disapproval. Poll results use the date the survey's fieldwork was done, as opposed to the date of publication.
